I've got the app on both my iPhone and my Android tablet, and the dongle to use with my Nikon D7000.

I actually ended up with two of the dongles, the first one they sent me didn't work, but it wasn't an issue with the dongle, but with the output(signal strength) of the iPhone. They released a software update which fixed the issue, but sent me a second gen dongle for my troubles.

I've been itching to get out and do some awesome night time lapse shots. The settings on the app are awesome.

I don't need it in my hands....the picture is right there. Cool thing about pictures: they give you an accurate representation of what something will look like. They've been doing it since 1822, or so I'm told.
